  • 본 연구는 생면산업 현장에서 주로 사용하고 있는 주정(ethanol)의 첨가에 따른 미생물의 증식변화와 유통기한 연장 효과를 과학적으로 평가해보고자 하였다. 이를 위해 ethanol을 0, 1, 2% 첨가하였으며, $10^{\circ}C$ 에서 저장하는 동안에 생면의 총균수의 변화를 측정하였다. 생면의 품질 기준인 6 log cfu/g을 적용하여 유통기한을 추산하였다. 그 결과 ethanol 첨가 생면의 유통 가능기한은 무첨가군의 경우 9.17일, 1% 첨가군의 경우 15.02일, 2% 첨가군의 경우 27.03일로 추정되어 무첨가군과 비교하여 63.8%, 194.8%의 유통기한을 연장효과를 보였다. 따라서, 생면에 주정(ethanol)의 첨가는 유통기한 연장에 효과적인 것으로 평가되었다.

  • 어묵의 유통기한을 예측하기 위해서 어묵을 30, 35, $40^{\circ}C$에서 각각 저장하면서 저장기간 중 총 호기성균 수를 측정하였다. Gompertz model을 이용하여 최대성장속도와 유도기를 구하였고, 각 parameter의 온도 의존성에 대한 식을 통해 유통기한에 관한 예측모델 식을 얻었다. 예측모델 식으로부터 계산된 유통기한은 0, 4, $10^{\circ}C$에서 각각 6.9, 5.5, 3.8일이었다. 이렇게 얻어진 예측모델 식의 적합성 평가를 위해 $A_f$$B_f$ 값을 산출한 결과, 각각 1.008, 1.003으로 나타나 예측모델식의 적합성이 뛰어났다. 이러한 결과로부터 본 연구에서 얻어진 유통기한예측 모델 식은 어묵의 유통기한 설정의 기초연구로써 활용될 수 있다고 판단된다.

  • 본 연구는 소비자들이 정보탐색을 하는데 있어 초기에 탐색되는 속성정보와 후기에 탐색되는 속성정보를 달리함으로써 소비자들의 최종대안 선택이 어떻게 변하는지를 파악하는데 목적이 있다. 연구결과, 컴퓨터에 대한 초기탐색 속성을 강화한 결과 고관여, 저관여 집단에서 모두 유의하게 최종대안 선택이 증가하는 것으로 나타났고 강화효과가 통계적으로 유의한 효과가 있음을 입증했다. 후기탐색 속성을 강화한 결과도 고관여, 저관여 집단에서 모두 유의하게 최종대안 선택이 증가했으며, 강화효과도 유의한 것으로 나타났다. 청바지 제품에 대한 초기속성을 강화한 결과 고관여집단에서는 최종대안 선택이 증가했으며, 강화효과도 통계적으로 유의한 결과를 보였다. 그러나 저관여집단의 경우는 초기속성 강화에 따른 최종선택 대안이 증가는 하였으나 통계적으로 유의하지는 않았다. 후기탐색 속성에 대한 강화효과는 고관여집단이나 저관여집단 모두에서 최종대안 선택변화의 증가를 가져왔으나, 통계적으로는 유의하지 않다는 사실을 확인하였다.

  • Purpose - This study reveals antecedent factors to help develop expressway rest areas in which employees were exposed to inferior environments, using Hackman and Oldham's Job Characteristics Theory. Research design, data, and methodology - The survey was conducted on 148 expressway rest area employees in Gyeonggi-do. After excluding questionnaires with invalid responses, 141 questionnaires were analyzed. Results - The sub-factors of job characteristics had a positive influence on the organizational commitment of employees, and organizational commitment had a positive influence on organizational citizenship behavior (OCB). Further, the results of mediation effects showed that organizational commitment and self-leadership were partially mediated. Finally, the results of the moderation effect of self-leadership showed that self-leadership was thought to be vital to let members endeavor to promote the competitiveness of expressway rest areas. Conclusions - The expressway rest area company needed to design jobs to let employees be self-motivated, productive, positive, responsible, and aspirational; job redesign, including job enrichment and job enlargement can be considerably helpful for affirmative influence.

  • Purpose - This study aims to explore the success of Lotte Mart in the global market, as well as examining the factors related to its entry methods. Research design, data, and methodology - This study analyzed the differences between Lotte Mart and E-mart in terms of their market entry methods, based on references and secondary data. This study is based on qualitative research that analyzes actual cases. Based on the results, this study analyzed and discussed actual cases based on references and secondary data, including newspaper interviews on Lotte Mart. Results - Lotte Mart succeeded in adapting to local markets it did this by ensuring the use of both mergers and acquisitions (M&As) and greenfield methods. In contrast, E-mart utilized only greenfield methods. Conclusions - The findings of this study may not be generalized to all industries, as only Lotte Mart was examined using the case analysis method. Therefore, the successful market entry modes of various companies should be explored in terms of FDI.

  • Purpose - This study aims to show that consignments can enable supply chain collaboration, based on the review of selected studies, and aims to investigate its potential to be a better collaboration program, through an analytical comparison with other collaboration initiatives. Research design, data, and methodology - This study uses a literature review on selected studies that researched consignments. In addition, based on the proposed framework, the current consignment process and other well-known collaboration programs are analyzed in terms of three key collaboration aspects. Results - Most studies employ simple research in terms of their purpose and methodology. An analysis with the proposed framework indicates the potential of consignments to foster supply chain collaboration. Conclusions - Based on the literature review, this study suggests that future research needs to aim for diverse research goals and conduct sophisticated research on consignments. An analysis with the proposed framework shows that consignments would be more effective for supply chain collaboration if active information sharing and joint decision-making are implemented.

  • Purpose - Based on the existing retail policy literature, this study aims to compare Korea with foreign countries, to propose better ideas for the Korean retail market. Research design, data, and methodology - It is necessary to analyze the existing retail regulations after categorizing them into several groups, depending on why governments have regulated retailers and the background for the retail policy. Results - Given that Korean retail regulations have focused on protecting conventional markets, comparing the retail policy objectives of South Korea and foreign countries is difficult. Conclusions - It is necessary examine how to protect independent stores, irrespective of store locations across the country. Rather than limiting the distance between traditional markets and the projected locations suggested by large retailers, various factors such as store size limit, opening and closing times, below-cost selling, land use planning, and competition tests are needed to protect small stores. Further, centralized authority for store operations should be delegated to local governments, to tackle the aggressive expansion of retail giants. To protect independent stores, political background is among the most important factors.
